There was a commotion outside in the wee hours of the morning, which turned out to be a bunch of fire engines, one of which settled right in front of our house, since we are guardians of a fire hydrant. We haven't found out what happened yet, but it must have been pretty routine, as they didn't hang around too long, and it's obvious nobody's house burned down. The weird thing is that someone hit a siren as they drove off, which seemed like an odd way to depart the scene of such a call, especially at 2:00 am, but if I had a siren like that I'd be using it whenever I could too.
